2 Claims.

This invention relates to roofs and roofin materials, and moreparticularly to a novel form of tile orv fabricated shingle and the roofcovering built up therewith.

The primary object of the invention is a stron durable roof which isweather tight, economical both of material and labor of installation,andattractive in appearance. 7

A further object of-the invention is a tile. shingle or roofing unitwhich is adapted to cooperate with similar units to form a tight roof inwhich a large portion of the unlt'is exposed to the weather.

A still further object of the invention is a novel means of fasteningthe individual units to the supporting structure and of locking theunits Section ll is for convenience termed a .body I section and sectionI! an exposed section. The

' tiles 22 comprising body sections only are emtogether to prevent theirdisplacement from'their installed position.

This invention includes among its features a roofing unit comprising asection adapted to be exposed to the weather and including in its uppersurface raised or embossed portions for deflecting the flow of waterfrom diflerent points thereon, a body portion directed at a slight'angleto the exposed section and adapted to underlie the succeeding course ofroofing units, and a transverse flange along the end of said bodyportion adapted to cooperate with fastening means attached to thesupporting structure.

Further features of the invention include an assembled roof structureformed of the novel roofing units in which one course of units tends todivert surface fiow thereon away from the joints of such course as wellas from the joints in the next lower course and in'which each course islocked against lifting by the cooperation of surface contacting portionsof one course with the otherwise free edge' of an adjacent course.

Further features of the invention will be readily apparent from anunderstanding of the preferred. form of the. invention hereinafter morefully described and illustrated in the accompanying drawing in whichFig. 1 is'an end view of a roof formed of the roofing units of thepresent invention;

Fig. 2 is a perspective view of a number of units assembled as in aroof; and

Fig, 3 is a perspective view of a single full roofing unit incorporatingthe features of the present invention.

played in the first or lowermost course of a roof assembly. Also lefthand-units, such as 24 and similar right hand half units (not shown),are employed in each alternate course laid in order to stagger the linesof juncture of the tiles of one course with respect to another. For thesame reason half width body tile units 26 are also employed.

As illustrated, all tile units are attached to the roof boards by meansof clamping strips 30. In a typical roof structure the first horizontalrow .or course of units laid is composed of a unit -28 at at least oneend of the row, with the As will readily .be' seen, the majority of thetile or shingle units are composed of two integrally formed flat,rectangular sections II and I2 arranged at a slight angle to oneanother.

necessary number of units 22 to cover the roof breadth. The secondcourse is composed of units which are so'laidas to entirely cover theunits 22 and 26 and to have their lines'of juncture staggered withrespect to-those of the latter units. The subsequent course is composedof units 24 and arranged with their lines of juncture staggered withrespect to the units of the preceding course and with their exposedsections butting'against the upper ends of portions i0 and ll of thepreviously laid row of units. The

subsequent rows of units are laid in a similarly obvious fashion untilthe ridge of the roof structure is approached. A suitable capping'member 28 spans opposite sides of the roof edge and projects downeither side thereof into abutting relation with the upper edges of theraised portions it and II of the last laid course of units.

As will be evident, adjoining raised or embossed portions i6 and I8divert water away from the juncture of the'adjoining units of the coursein which they form a part, whereas the raised portions 2| divert thewater from the line of juncture of the units in the course below them.Any small amount of water which does pass between units will have itsline of flow directly 7 toward the apex of a raised portion 2| which,

as already stated, simply diverts the flow of such water away i'rom theline of juncture of .th two units meeting below portion 2|.

The portions I and I8 by butting against the lower ends of theexposedsections litend to ill-- vert up-moving wind currents over such sectionsthereby materially reducing the danger-of the tiles being lifted by thewind. Also, as will be evident i'rom a consideration of Fig. 1, thepresence of raised portions I and II on the surface of a section I!results in a-positive locking of the units in the position in which theyare originally laid so long as the uppermost course of units is held inposition by cap 28, .Any attempt to lift an intermediate or lower courseof units tends to cause the next higher course to rotate about itsfasten- -ing II as a center and, since the points of rotatlon ofadjacent courses are separated by a distance equal to less than half thelength of each unit, the lower edge of the upper unit tends to slidetoward the lower end of the unit being raised, i. e., the radii drawnfrom the centers of rotation to the point of intersection tend toequalize. Such sliding movement is positively opposed by abutment of thefree ends of each course against the raised portions I and I. of i thenext lower course and accordingly all lifting of units throughout theentire root is prevented. Although in the foregoing there has been shownand described the preferred embodiment of the invention, it is to beunderstood that minor changes in the details of construction andcombination of units may be resorted to without departing from thespirit and scope of the invention as claimed.

I claim: 1. In a roof structure successive courses of rooilng tile withthe line of jimcture of the respective tiles of one course staggeredwith respect to those of the succeeding course and the respective tilesof each course having inverted right angled triangular surface portionswith their altitudes located along the lateral edges of clamping meanscooperative with the lip-turned ends of said units to hold them on theroof structure, a second course of units overlapping those of the firstcourse and in staggered relation thereto, the units of said secondcourse having embossed areas with surfaces for diverting water flowingthereover in directions away from their lateral edges, a third course ofunits overlapping those of the second course and in staggered relationthereto, the lower ends of the units of the third course abutting theareas of the second course of units and themselves having embossed areaswith surfaces for diverting water flowing thereover in directions awayfrom the lines of juncture of the respective units of the tiles oi thesecond course.
